TUBE-CUTTER.

SPECIFICATION formingpart of Letters Patent-N0. 772,062, dated October 11, 19M. Applicetion filed November 10, 1903. Serial No. 180,515. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN J. Room, a citizen of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Tube-Cutters, of which the following is a specification.

This invention relates to tube-cutters, and has for its object to construct a tool of this character which will be easy to manufacture and one that can be easily operated. a

The invention consists of certain new and novel forms of construction that have not been used before in devices of this kind, and thereby making it more practical for the purpose intended.

With the above and other objects in view the invention consists in the details of construction, combination, and arrangement of parts hereinafter more fully described and claimed.

In describing the invention in detail reference will be had to the accompanying drawings, forming a part of 'this specification, wherein like characters denote corresponding parts throughout the specification, and in which- Figure 1 is a side view of tube-cutter and showing tubing in dotted lines. Fig. 2 is a top plan view thereof. Fig.3 is a longitudinal section view taken on the line 3 3 of Fig. 2. Fig. et is an end view of cutter-head.

In the drawings numeral 5 is' cylindrical cutter head. This is connected to a crosshead 6 by rods 7, that pass through the cutter-head, as shown in dotted lines in Fig. 1. The end of screw-rod 8 that passes through cutter-head is threaded in the cross-head 6 and is wedge-shaped, as at 8. This is for the purpose of raising the block 9, that has journaled therein the cutting-disk 10. This is a swivel-joint at the junction of the threaded rod 8 and the wedge portion 8 thereof, as shown at 8 The block 9 is formed with ridges 11, that fit into corresponding grooves 12 of cutter-head, as by this means of construction the block will not bind against walls of cutter-head when forced upward by the tapered wedge 8.

To raise the block 9 for the purpose of taking up the lost space in cutting, release the jam-nut 13, as shown in dotted lines of Fig. 3, and revolve operating-wheel 14:, thereby forcing the wedge 8 against theunder face of block 9, thus elevating the same until the cutting-disk comes in contact with tubing, after which the jam-nut is screwed against the crosshead 6, and it is then ready for operating.

The screw-rod 8serves a double purpose that is, in cutting and also for the adjustment of cutting-disk. Byusing the rods 7 in connection with the cross-head in revolving the cutter it takes the direct strain from the tapered wedge 8',v and, again, the rods being some distance from the center more leverage is acquired, thereby making the cutting much easier.

i I, also provide the cutter-head with a pair ofrollers 15, which serve as a bearing-surface for the head and allowing of a free and easy motion thereto.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a tube cutter, a cutter head, a wedge slidable therein, blocks slidable in the head and engaged by the wedge, cutter-wheels journaled in the blocks, rods seated and adjustable in the end of the head,ga-crosshead on the rods and a feed-screw threaded in the cross-head, substantially as described.

In testimony whereof I aflix my signature, in the presence of two witnesses, this 5th day of November, 1903.

JOHN J. ROUSH.
